System and method for perturbing a permanent magnet asymmetric field to move a body

ABSTRACT

A system and method for perturbing a permanent magnet asymmetric field to move a body includes a rotating body configured to rotate about a rotation axis, a permanent magnet arrangement arranged on the rotating body containing two or more permanent magnets, and a perturbation element. The permanent magnet arrangement is configured such that an asymmetric magnetic field is generated by the permanent magnets about a perturbation point. Actuation of the perturbation element at or near the perturbation point causes a tangential magnetic force on the rotating body and/or the permanent magnet arrangement, thereby causing the rotating body to rotate about the rotation axis. The disclosure may also be used for linear motion of a body.

DETAILED DESCRIPTION

As discussed in more detail below, in some embodiments, the presentdisclosure is directed to systems and methods for perturbing a permanentmagnet asymmetric field to provide motion of a body. The systems andmethods of the present disclosure may use permanent magnets of any shapeand size, based on the desired design parameters and may be configuredwith or without a housing. The present disclosure has a permanentmagnetic arrangement resulting in an asymmetric magnetic field havingpotential energy stored in the magnetic field based on the magnetic (orflux) circuit configuration.

We have found that a small applied input force by a perturbation elementthat perturbs the asymmetric field causes a release of potential energyby the permanent magnet configuration that results in an output forcegreater than the applied input force (or force amplification), therebyproviding a permanent magnet driven (or assisted) force amplifier.

Referring to FIGS. 1 and 2, an exemplary embodiment of a permanentmagnet asymmetric field system 100A is shown in accordance withembodiments of the present disclosure. The system 100A includes arotating body (such as a flywheel) 102, a permanent magnet arrangement104 having a plurality of permanent magnets 106, and a perturbationelement (or a control rod or driver pin) 108. The rotating body 102 isconfigured to rotate about a rotation axis 110. The rotating body 102 isshown as being a connected to an alternator/generator 112, by a shaft125, which may be attached to the body 102 by a bolt 123 or the like.Also, the alternator/generator 112 may have vent holes 121 to avoidoverheating.

In this embodiment, the perturbation element 108 is a steel screw ornail or rod or pin constituting a ferrous body made of a ferrousmaterial. This embodiment is shown with optional rests (or seats) 107 inthe form of sockets for the tips of the perturbation elements 108. Therests 107 may be formed of plastic and/or metal, or any other material,or, in some embodiments may be divots or indentations in the bottomplate 102.

The permanent magnets 106 of the arrangement 104 are fixedly arranged on(or attached to) the rotating body 102 such that an asymmetric magneticfield is generated, with a resultant major magnetic field 114 (or majorfield 114) and minor magnetic field 115 (or minor field 115), about oneor more perturbation points 116A, 116B, 116C, 116D (collectively “116”).Each perturbation point 116 has a cluster of four magnets 106circumferentially surrounding the perturbation point 116, with eachmagnet 106 having an equal radial distance from the perturbation point116 or substantially equal distance. Some clusters share one or morecommon magnets 106. In each cluster of magnets 106, there are threemagnets 106 with an upper surface having the same north (N) polarityfacing away from the rotating body 102 generating a major field and onemagnet 106 with an upper surface having a south (S) polarity facing awayfrom the rotating body 102 generating a minor field 115. Eachperturbation point 116 has a perturbation axis 118 that is substantiallyparallel to the rotation axis 110. Also, there is a common magnet 106Alocated in the center of the configuration, about which the body 102rotates.

If the body 102 (or bottom plate) is steel the magnets 1067 may bemagnetically fixed or attached to the body 102; otherwise, the magnets106 may be fixed to the body by bolts, glue, clamps, or other attachmentmeans. They may also be embedded into the body if desired.

For the purposes of the present application, an asymmetric magneticfield comprising a “major” field and a “minor” field, with the majorfield 114 being larger in size than the minor field 115 and/or the majorfield 114 having a magnetic field strength greater than the minor field115. In this embodiment, the magnets form a co-planar matrix pattern toform an H-pattern magnetic flux line of the major field 114. While thisembodiment shows there being a greater number of magnets 106 forgenerating the major field 114 than the number of magnets 106 forgenerating the minor field 115, it is within the scope of the presentdisclosure for there to be a great number of magnets 106 for generatingthe minor field 115. For example, the magnets 106 generating the major114 field may be less in number but “stronger” than the greater numberof “weaker” magnets 106 generating the minor field. The magnets 106 foreither field 114, 115 do not need to be of the same shape, size orstrength, and there may be different magnet types/shapes for one or bothfields 114, 115.

In this embodiment, the flywheel rotating body 102 is about 15″diameter×1.25″ thick and is about eighty (80) pounds and is aautomotive/truck flywheel. However, other size, shape and weightrotating bodies 102 are within the scope of the present disclosure. Thealternator/generator 112 is a forty-eight (48) volt permanent magnetgenerator, model FREEDOM PMG made by Missouri Wind and Solar thatreaches battery voltage at 266 rpm. However, other types ofalternators/generators are within the scope of the present disclosure.

Various housing and magnet configurations are within the scope of thepresent disclosure. For example, and without limitation, the housingenclosing the permanent magnets 106 may be an enclosed high ferroussteel cylinder having an 8″ outer diameter×7″ inner diameter×2″ heightcapped with an 8″ diameter×¼″ thick ferrous steel disc on the bottom anda 8″ diameter×¼″ thick aluminum cap on the top. As described herein, thecap, bottom, and sides) may be made of a ferrous material or non-ferrousmaterial. The permanent magnets 106 may be, for example and withoutlimitation, 1-1.25″ diameter×0.5″ thick (or high) NdFe/cylindrical rareearth magnets, magnetized axially (or vertically). The permanent magnets106 can be purchased “off-the-shelf” from K&J Magnetics, Part NumberDX48.

In operation, when the perturbation element 108 is arranged at aperturbation point 116 (or near a perturbation point 116) in an initialposition such that a longitudinal extension of the perturbation element108 is parallel to the perturbation axis 118 (or perpendicular to asurface of the rotating body 102 at the perturbation point 116) and thenactuated to deviate from the perturbation axis 118 through a providedinput force (or applied force) in a direction 120A, 120B, 120C, 120Dtowards a central point of the minor field 115 and/or a central point ofthe magnet(s) 106 generating the minor field 115. A deviation 119 fromthe perturbation axis 118 is shown in FIG. 1. The perturbation element108 may be inserted at a substantially central part of the perturbationpoint 116, but systems and methods may work when the perturbationelement 108 is radially offset from the central part of the perturbationpoint 116. In this embodiment, the central point of the minor field 115is in alignment with the central point of the magnet 106 having a southpolarity (S) facing away from the rotating body 102 (or bottom plate).The actuation of the perturbation element 108 to deviate away from theperturbation axis 118 in this manner causes a distortion (orperturbation) of the asymmetric field 114, 115 and generates a resultingtangential magnetic force on the permanent magnet arrangement 104 and/orthe rotating body 102 about the rotation axis 110, thereby causing therotating body 102 to rotate about the rotation axis 110 in either acounter-clockwise direction 122 or clockwise direction 124 assuming thetangential magnetic force is greater than the friction and/or loadresisting the tangential magnetic force. Advantageously, the permanentmagnet arrangement 104 allows for counter-clockwise direction 122rotation and clockwise direction 124 rotation, which may be considered aforward and reverse option of bi-directionality.

In some embodiments, rotation of the rotating body 102 may be caused byactuation of the perturbation element 108 to deviate from theperturbation axis 118 in any direction. For example, a wobble of a fewdegrees of the perturbation element 108 from the perturbation axis 118will also cause rotation of the rotating body 102.

In embodiments according to the present disclosure, the input forcerequired to actuate the perturbation element 108 to deviate from theperturbation axis 118 is less than the resulting tangential magneticforce acting on the rotating body 102. This is possible due to thepotential energy contained in the permanent magnet arrangement 104 thatgenerates a tangential magnetic force to drive the rotating body 102 torotate about the rotation axis 110 that is larger than the input force(or applied force) provided. Thus, the present disclosure provides apermanent magnetic-driven force amplifier.

The rotation of the rotating body 102 may be used for any applicationfit for a rotating body to perform work, such as, for example,generating electricity, propelling an automobile, driving a propeller ofa boat or airplane, and the like. For example, embodiments according tothe present disclosure may facilitate rotation in wind turbines,significantly reducing the input energy required at startup to generateelectricity, particularly at low wind speeds. Embodiments may facilitaterotation in horizontal wind turbines (or HAWT) or vertical wind turbines(or VAWT). Embodiments according to the present disclosure may becoupled with a flywheel and an alternator or generator of a windturbine. Embodiments according to the present disclosure may be used inresidential, commercial, and/or utility scale use applications.

The rotating body 102 may be caused to rotate as described by theperturbation of the asymmetric field by the single perturbation element108. However, any number of perturbation elements 108 may be actuated attheir respective perturbation points 116. For instance, a firstperturbation element 108 may be actuated at the perturbation point 116Awhile a second perturbation element 108 is simultaneously (orsubstantially simultaneously) actuated at the perturbation point 116D todrive the rotating body 102 in a counter-clockwise direction. Similarly,a third perturbation element 108 may be actuated at the perturbationpoint 116B while a fourth perturbation element 108 is simultaneously (orsubstantially simultaneously) actuated at the perturbation point 116C todrive the rotating body 102 in a clockwise direction. While theadditional perturbation elements 108 are shown as being actuated atopposing perturbation points 116, in other embodiments the additionalperturbation elements 108 are not at opposing perturbation points 116about the rotation axis. For example, the perturbation elements 108 maybe at perturbation points 116 at 30°, 45° or 90° angular separation.However, any other degree of angular separation is within the scope ofthe present disclosure. Depending on the number of magnets 106 andshape/configuration of the permanent magnet arrangement, there may beany number of perturbation elements 108 and/or perturbation points 116.The additional perturbation elements 108 and perturbation points 116provide the ability to provide additional tangential magnetic force tothe rotating body 102 depending on the strength of the magnets 106.

The magnets 106 shown and described in the embodiment of FIGS. 1 and 2are cylindrical magnets. However, any type or shape of magnet is withinthe scope of the present disclosure. For example, the magnets 106 may berectangular bar magnets, circular flat (or disc) magnets, or the like.

While the perturbation elements 108 has been shown and described asbeing a steel screw, it is within the scope of the present disclosurefor the perturbation element 108 to be virtually any size and shape, andbe made of any ferrous material, such as, for example, steel, steelalloys, iron, iron alloys, and the like. The perturbation element 108may also be a permanent magnet, such as, for example, a conical magnet,a cylindrical magnet, or the like. A perturbation element 108 in theform of a magnet may provide for greater amplification of the inputforce (or applied force) by providing greater distortion or perturbationof the asymmetric magnetic field than a similar mass, size and/or shapeferrous body perturbation element 108. The mass, size and shape of theperturbation element 108 may be adjusted as desired to achieve thedesired magnetic field perturbation properties of the perturbationelement 108, for example, strength or tuning the amount of tangentialmagnetic force per degree or distance of actuation 119 of theperturbation element 108. In some embodiments, greater amplification ofthe input force may be achieved by arranging a bias magnet to theferrous control rod with the same polarity as the polarity of the sideof the magnets 106 facing away from the rotating body 102 that generatethe minor field 115 is arranged on the upper, or distal end, of theperturbation element 108.

Referring to FIG. 3, a permanent magnet asymmetric field system 100B isshown that is substantially the same as the permanent magnet asymmetricfield system 100A of FIGS. 1 and 2 except that two of the magnets 106are removed. In this embodiment, the system 100B only has two clustersof four magnets 106 surrounding two perturbation points 116B, 116C witha common central magnet 106A. The system 100B operates in the samemanner under the same principles as shown and described above inconnection with the system 100A FIGS. 1 and 2. One difference betweenthe system 100B shown in FIG. 3 and the system 100A of FIGS. 1 and 2, isthat the permanent magnet arrangement 104 of the system 100B onlygenerates an asymmetric field 114, 115 about two perturbation points116B, 116C that can be perturbed to generate tangential magnetic forces120B, 120D, which result in rotation in the same direction, theclockwise direction 124.

Referring to FIG. 4, a permanent magnet asymmetric field system 100C isshown that is substantially the same as the permanent magnet asymmetricfield system 100A of FIGS. 1 and 2 except that five of the magnets 106are removed. In this embodiment, the system 100C only has one cluster offour magnets 106 surrounding one perturbation point 116C and the bodyrotates about the center of the magnet 106A. The system 100C operates inthe same manner under the same principles as shown and described abovein connection with the system 100A FIGS. 1 and 2. One difference betweenthe system 100C shown in FIG. 4 and the system 100A of FIGS. 1 and 2, isthat the permanent magnet arrangement 104 of the system 100C onlygenerates an asymmetric field 114 about one perturbation point 116C thatcan be perturbed to generate a tangential magnetic force 120D, whichresults in rotation in one direction, the clockwise direction 124.

Referring to FIGS. 5 and 6, a permanent magnet asymmetric field system100D is shown that is substantially the same as the permanent magnetasymmetric field system 100A of FIGS. 1 and 2. The system 100D includesan actuation input device 200. In this embodiment, the actuation inputdevice 200 is an electric motor having an output shaft configured torotate two actuation arms 202A, 202B (collectively “202”) about anactuation rotation axis 204 that is substantially parallel to or thesame as the rotation axis 110. The actuation input device 200 is inoperative communication with a controller 206 configured to control theactuation force provided by the actuation arms 202 and the timing oftheir actuation. The electric motor 200 is a twelve (12) volt DChigh-rpm, low-torque direct current motor, model XD-3420, DC 12 volt,3,000 RPM, similar to that used in radio controlled cars and toys andsmall industrial actuator applications.

Referring to FIG. 7, a permanent magnet asymmetric field system 100E isshown that is substantially the same as the permanent magnet asymmetricfield system 100D of FIGS. 5 and 6. The system 100E includes a forceassist device 208 that applies force (or pressure) against the actuationarms 202. The force assist device 208 distributes the weight of athreaded weighted-element 210 (e.g. 2.2 lbs) through a threaded drivescrew mechanism 212 such as a spiral gear or helical gear with highhelix angle cause against the arms 202 to apply a force against the pins108. The assistance of the force assist device 208 maintains against thepins 108 by against the arms 202 to assist the motor and to reduce theimpact of vibrations or disturbances from causing a separation of thearms 202 from the perturbation elements 108 that would otherwise causenon-uniform rotation of the rotating body 102. While the force assistdevice 208 in this embodiment is a “gravity” type force assist device,other force assist devices that utilize active force assist are withinthe scope of the present disclosure. In that case, the motor shaft 216and screw drive shaft 212 both drive the arms 202A to put force on theperturbation pins 108.

Referring to FIGS. 8, 9 and 16A-16F, a permanent magnet asymmetric fieldsystem 100F is shown in accordance with embodiments of the presentdisclosure. The system 100F includes two permanent magnet arrangements104A, 104B arranged on the rotating body 102, each of the arrangements104A, 104B having four permanent magnets 106 around a perturbation point116E, 116F, and having the perturbation element 108 extending from thesame, similar to the system 100B of FIG. 3 except that the arrangements104A, 104B do not share any common permanent magnets in the clusters (orpermanent magnetic arrangements) surrounding the perturbation points116E, 116F. The arrangements 104A, 104B are arranged radially offsetfrom the rotation axis 110. It is within the scope of the presentdisclosure to configure the permanent magnet arrangement(s) 104 tolocate the perturbation point(s) 116 at a desired radial distance (d),e.g. 8 inches, from the rotation axis 110. The boundary lines 902, 904approximate the magnetic boundary field lines between the majority northfield and the minority south field in the arrangements 104A, 104B. Thearrangement of the magnets 106 generates a magnetic field force thatforces a perturbation element 108, if present, towards a defaultdirection D. The perturbation and operation of the arrangements 104A,104B are substantially as discussed above in connection with otherembodiments. One or both of the perturbation points 116E, 116F may havethe perturbation element 108 actuated therein in order to perturb theasymmetric magnetic field(s). The resulting tangential magnetic forces320A, 320B from the perturbation(s) on the arrangements 104A, 104B,which is in a direction opposite to the default direction D, will causethe rotating body 102 to rotate about the rotation axis 110. Eacharrangement 104A, 104B is arranged in an optional housing 300A, 300B.Also, any number of the arrangements 104A or 104B may be disposed aroundthe perimeter of the rotating body 102.

A schematic cross-sectional view of the permanent magnet arrangement104B along line 16A is shown in FIG. 16A; along line 16B in FIG. 16B;along line 16C in FIG. 16C; along line 16D in FIG. 16D; along line 16Ein FIG. 16E; and along line 16F in FIG. 16F. As shown in FIGS. 16A-16F,when a ferrous body perturbation element 108 is arranged at theperturbation point 116F, the perturbation element 108 has an oppositepolarity as the polarity of the magnet 106 at a portion of theperturbation element 108 facing the permanent magnet 106. For example,as shown in FIG. 16A, the top left portion of the perturbation element108 has a north polarity as it is facing the left permanent magnet 106,which has a south polarity at that height (in the direction of theextension of the perturbation element 108); and the bottom left portionof the perturbation element 108 has a south polarity as it is facing theleft permanent magnet 106, which has a north polarity at that height.This polarity pattern is true for each portion of the perturbationelement 108 facing each magnet 106.

Each arrangement 104A, 104B is enclosed in a 5″ outer diameter×4″ innerdiameter×1.5″ height enclosed ferrous steel cylinder housing 300A, 300Bcapped on top with a 5″ diameter ¼″ thick aluminum disc and a bottomplate of same dimensions made of steel. However, as discussed herein,other housing 300A, 300B configuration shapes and sizes are within thescope of the present disclosure. Also, as discussed above, the housings300A, 300B are optional and the permanent magnets 106 may be arranged orfixed directly on the rotating body 102. In this embodiment, therotating body 102 is the 801 b flywheel discussed hereinbefore. However,other rotating body 102 size, shape and materials are within the scopeof the present disclosure. The rotating body 102 may be made of ferrousor non-ferrous materials.

Also, the motor drive and/or spiral gear arrangement with rotating armsto press against the perturbation pins 108 shown in FIGS. 5-7 may beused with this embodiments of FIGS. 8 and 9.

Referring to FIGS. 10 and 11, a permanent magnet asymmetric field system100G is shown in accordance with embodiments of the present disclosure.The system 100G includes a cylindrically-shaped rotating body 402, aplurality of wall magnets 406, two cylindrical bias magnets 407A, 407B(collectively “407”) and a perturbation element 408. The rotating body402 is configured to rotate about a rotation axis 410. The wall magnets406 are arranged on an inner circumferential wall 412 of the rotatingbody 402. The wall magnets 406 on one side of an imaginary equator 414that bifurcates the rotating body 402 have a side facing the rotationaxis 410 with a north polarity (N) and the wall magnets 406 on theopposite side of the imaginary equator 414 have a side facing therotation axis 410 with south polarity (S). The bias magnets 407 arearranged at the perturbation points 416 on a bottom surface 418 of therotating body 402, are aligned on an “equator” 414 and are radiallyoffset from the rotation axis 410. The upper surfaces of the biasmagnets 407 facing away from the bottom surface 418 have differentpolarities. In particular, the upper surface of the bias magnet 407A hasnorth polarity (N) and the upper surface of the bias magnet 407B hassouth polarity (S).

In some embodiments, the wall magnets 406 are rectangular permanentmagnets that are 3″ long, ½″ wide and ¼″ thick; the bias magnets arecylindrical magnets that are ¼″ diameter and ⅛″ thick; the housing hasan outer diameter of 4″, an inner diameter of 3.5″ and a height of 4″.The housing has an open top, but fully enclosed cylinders orcylindrically-shaped housings are within the scope of the presentdisclosure as are other shapes such as rectangles, ovals, triangles,etc. In some embodiments, the housing is made of a ferrous material andin other embodiments the housing is made of a non-ferrous material. Insome embodiments, the housing has some ferrous material and somenon-ferrous material, e.g., a cylindrically-shaped housing with a wall412 and bottom surface 418 made of a ferrous material (e.g., steel) anda top made of a non-ferrous material (e.g., plastic or aluminum).However, other dimensions, shapes and material choices are within thescope of the present disclosure and may be changed as the applicationrequires or is desired.

The wall magnets 406 and bias magnets 407 generate a magnetic flux fieldline 420A that deviates from the equator 414 near the bias magnets 407,but intersects the equator 414 substantially near the point where therotation axis 410 intersects the equator 414. Specifically, the magneticflux field line 420A deviates from the equator 414 towards the wallmagnets 406 having a side facing the rotation axis 410 that is ofopposite polarity to the upper surface of the bias magnets 407. Theconfiguration of the magnetic flux field line 420A causes twoperturbation points 416 located substantially at the location of thebias magnets 407. The bias magnets 407 may be located about a third ofthe distance from the inner walls to the center of rotation 410.

In operation, the perturbation element 408 is inserted into the rotatingbody 402 at (or substantially at) either of the perturbation points 416such that a longitudinal extension of the perturbation element 408 isparallel or substantially parallel to the rotation axis 410. Theperturbation element 408 is then actuated to move or tilt toward themagnetic flux field line 420A in the direction 430A. The actuation ofthe perturbation element perturbs the asymmetric magnetic flux fieldline 420A and generates a resulting tangential magnetic force on thewall magnets 406, bias magnets 407 and/or the rotating body 402 aboutthe rotation axis 410, thereby causing the rotating body 402 to rotateabout the rotation axis 410 in a counter-clockwise direction 422assuming the tangential magnetic force is greater than the frictionand/or load resisting the tangential magnetic force. As discussed abovein connection with other embodiments, there may be an additionalperturbation element 408 (not shown) such that there is a perturbationelement 408 actuated at both perturbation points 416 simultaneously, ifdesired, which may provide twice the rotational force on the body 402.

In some embodiments, the upper surface of the bias magnets 407 may havethe same polarity (N-N; or S-S). In such embodiments, for a N-Narrangement, the magnetic flux field line would have the shape of themagnetic flux field line 420B on the right side of the axis 410. Thisconfiguration allows for bi-directional rotation of the body 402. Forinstance, a perturbation element 408 actuated at the perturbation point416 at the bias magnet 407A, in the direction 430A, would causecounter-clockwise 422 rotation of the rotating body 402, while actuationof the perturbation element 408 (or actuation of a second perturbationelement 408) at the perturbation point 416 at the bias magnet 407B, inthe direction 432B, would cause clockwise 424 rotation of the rotatingbody 402.

One of the two bias magnets 407 is optional and may be removed. Forexample, if the bias magnet 407B is removed, then the magnetic fluxfield line 420A would only deviate from the equator substantially at thesingle bias magnet 407A. In this embodiment, there would only be oneperturbation point 416 at the single bias magnet 407A.

Referring to FIG. 12, a permanent magnet asymmetric field system 100H isshown in accordance with embodiments of the present disclosure. Thesystem 100H includes a rotating body 502, a permanent magnet arrangement504 having a plurality of magnets 506 similar to the arrangements 300A,300B in FIGS. 8 and 9 and a perturbation element 508. The system 100Hfurther includes a perturbation element guide (or support) 510 defininga perturbation element opening 512. The perturbation element opening 512is configured to receive the perturbation element 508 and is locatedaround a perturbation axis 514 that would cause motion of the rotatingbody 502 if the perturbation element 508 is actuated to deviate from theperturbation axis 518 or towards a magnetic flux field line as discussedherein in connection with other embodiments. The perturbation elementguide 510 serves to limit the range of deviation of the perturbationelement 508 from the perturbation axis 514 (or distance 119 (FIG. 1)from a magnetic flux field line). The guide 510 may advantageouslyprevent the perturbation element 508 from by an actuating device such asan electric motor and/or gravity weight such as in FIGS. 5-7, i.e.,being actuated by a distance greater than required or desired. The guide510 may also advantageously constitute a stop to prevent theperturbation element 508 from being moved by the magnets 506 when theperturbation element 508 is not being actuated or held by an actuatingdevice. The guide 510 may be a cover or cap with a hole 512 and may beused with any embodiment herein to limit the range of motion of theperturbation element 508.

The perturbation element opening 512 may be any size or shape as isdesired or as the application requires. For example, the perturbationelement opening 512 may be a circular hole, a straight slot, a curvedslot or a zig-zag slot. However, other shapes are within the scope ofthe present application.

Referring to FIG. 13, while the embodiments discussed above have been inconnection with systems having a rotating body that rotates about arotation axis, permanent magnet asymmetric field systems that generatenon-rotation motion (e.g. translational or linear motion) are within thescope of the present disclosure. For example, referring to FIG. 13, apermanent magnet asymmetric field system 100I is shown in accordancewith embodiments of the present disclosure. The system 100I includes alinear motion body 602 having a plurality of bearings (or wheels) 603, apermanent magnet arrangement 604 having a plurality of magnets 606, anda perturbation element 608. The permanent magnet arrangement 604generates a major field and minor field as discussed above in connectionwith other embodiments. When the perturbation element 608 is deviated ormoved towards the minor field in a direction 610, the resulting magneticforce on the magnets 606 and/or the linear motion body 602 causes thelinear motion body 602 to move in the direction 612. The bearings 603serve to reduce the friction or resistance the linear motion body 602may encounter in being forced to move in the direction 612.

The linear motion body 602 is shown as being arranged in an optionallinear track 614 which may have guard rails. The linear track 614confines the linear motion body 602 to prevent the linear motion body602 from moving in any non-linear directions from the track 614. Thebi-directionality discussed above in connection with rotatingembodiments is also applicable to linear motion embodiments. Inparticular, there may be a magnet arrangement where perturbation of theperturbation element 608 (or a different perturbation element) causesthe linear motion body 602 to move in the opposite linear direction,thereby giving a forward and reverse control of the system 100I.

Referring to FIGS. 14, 15 and 17A-17F, a permanent magnet asymmetricfield system 100J is shown in accordance with embodiments of the presentdisclosure. The system 100J includes two permanent magnet arrangements104C, 104D arranged on the rotating body 102, each of the arrangements104C, 104D having five permanent magnets 106 around a perturbation point116G, 116H. The central permanent magnet 106J of each arrangement 104C,104D is arranged at the respective perturbation point 116G, 116H. Thearrangements 104C, 104D are arranged radially offset from the rotationaxis 110. It is within the scope of the present disclosure to configurethe permanent magnet arrangement(s) 104 to locate the perturbationpoint(s) 116 at a desired radial distance (d), e.g. 8 inches, from therotation axis 110. The boundary lines 152, 154 approximate the magneticboundary field lines between the majority north field and the minoritysouth field in the arrangements 104C, 104D. The arrangement of magnets106 generates a magnetic field force that forces a perturbation element108, if present, towards a default direction D. The perturbation andoperation of the arrangements 104C, 104D are substantially as discussedabove in connection with other embodiments. One or both of theperturbation points 116G, 116H may have the perturbation element 108actuated therein in order to perturb the asymmetric magnetic field(s).The resulting tangential magnetic forces 320C, 320D from theperturbation(s) on the arrangements 104C, 104D, which is in a directionopposite to the default direction D, will cause the rotating body 102 torotate about the rotation axis 110. Each arrangement 104C, 104D isarranged in an optional housing 300C, 300D. Also, any number of thearrangements 104C or 104D may be disposed around the perimeter of therotating body 102.

A schematic cross-sectional view of the permanent magnet arrangement104D along line 17A is shown in FIG. 17A; along line 17B in FIG. 17B;along line 17C in FIG. 17C; along line 17D in FIG. 17D; along line 17Ein FIG. 17E; and along line 17F in FIG. 17F. Similar to the polarity ofthe perturbation element 108 when arranged in the permanent magnetarrangement 104B shown in FIGS. 16A-16F, as shown in FIGS. 17A-17F, whena ferrous body perturbation element 108 is arranged at the perturbationpoint 116H, the perturbation element 108 has an opposite polarity as thepolarity of the magnet 106 at a portion of the perturbation element 108facing the permanent magnet 106. For example, as shown in FIG. 17A, thetop left portion of the perturbation element 108 has a north polarity asit is facing the left permanent magnet 106, which has a south polarityat that height (in the direction of the extension of the perturbationelement 108); and the bottom left portion of the perturbation element108 has a south polarity as it is facing the left permanent magnet 106,which has a north polarity at that height. This is true for each portionof the perturbation element 108 facing each magnet 106. In contrast tothe polarity pattern shown in FIGS. 16A-16F, due to the perturbationelement 108 in FIGS. 17A-17F being arranged above or at the centralpermanent magnet 106J, the portion facing central permanent magnet 106Jwill have a polarity opposite to the polarity of the side of the centralpermanent magnet 106J facing the perturbation element 108. In this case,the side of the central permanent magnet 106J is north and, thus, thepolarity of the bottom portion of the perturbation element 108 facingthe central permanent magnet 106J is south.

Referring to FIG. 15, the four outer magnets 106 may be cylindrical (ordisc) magnets having a diameter of 1¼″, and a thickness (or height)of/2″ and the center bias magnet 106J may be a cylindrical (or disc)magnet having a diameter of ¾″, and thickness (or height) of ¾″. Thebias magnet 106J may be centered geometrically in the configuration toprovide the most efficient and effective operation; however, if the biasmagnet 106J is not centered, the system 100J will still operate, but maybe less efficient and/or effective. The space between the magnets 106may be made as small as possible or may be zero (i.e., touching),depending on the desired performance. The closer the spacing, thestronger the resultant magnetic field strength on the perturbationelement 108 and more magnetic energy may be provided and the lessdisplacement is needed (and more input force) on the perturbationelement (or actuator) 108 to initiate motion. Also, the magnets 106,106J may be any shape, e.g. round, oval, square, rectangular, triangle,parallelogram, or any other polygon shape, as long as the polarities arethe same as that described herein. For example, the outer magnets 106may be rectangular magnets having a length of 1″ a width of/2″ and athickness (or height) of ¾″. In some embodiments, displacement of theperturbation element (or actuator) 108 by 1 mm-2 mm is sufficient togenerate motion.

Also, the ferrous body perturbation element (or actuator) 108, may berounded or come to a point or a rounded point at the end (or pivotingend) that touches (or contacts) the bias magnet 106J. The ferrous bodyperturbation element 108 acts as a flux concentrator in the region wherethe pivoting end contacts the bias magnet 106J. In particular, themagnetic field is concentrated in the pointed tip of the pivot end whichis shown as a south S polarization (but may have a north N polarizationin other embodiments). This polarization creates a localized magneticfield between the element 108 and the bias magnet 106J, which increasesthe magnetic field strength and the resulting magnetic attraction orattractive magnetic forces, thereby enhancing the effect of an appliedforce to create motion. Also, thereby may be a small divot (not shown)in the center of the magnet 106J for the perturbation element 108 tip torest to avoid sliding. Such a divot may also be used in the system ofFIG. 8 to keep the perturbation element 108 at the perturbation point116.

As discussed herein, when an input force is applied to the element 108,it perturbs the asymmetric field to cause a release of potential energyto cause motion (rotational or translational). As also discussed herein,systems according to the principles of the present disclosure mayoperate using magnetic attraction forces acting between the perturbationelement 108 and the magnets in the system.

Also, if the polarity of the bias magnet 106J is reversed, the systemwill rotate or translate in the opposite direction. Also, the substrate102 that the magnets are mounted to may be made of a non-ferrousmaterial (e.g., plastic) or a ferrous material.

Referring to FIG. 18, is a diagram of the magnetic flux density from theminor field to the major field along the upper surface of a centralpermanent magnet (or bias magnet) 106J of the permanent magnetarrangement 104D of the permanent magnet asymmetric field system 100J ofFIG. 14 in accordance with embodiments of the present disclosure. Thediagram plots recorded magnetic flux density values of an exemplarysystem according to the system of FIG. 14, in which the recordedmagnetic flux density is at 3.25 kG at one edge of the central permanentmagnet 106J close to the minor field south S side and decreases to 2.0kG at the opposite side of the magnet 106J close to the major fieldnorth N. The magnetic flux density is at 2.5 kG at the center of thecentral permanent magnet 106J. When the bias magnet 106J is measuredalone (outside of the system 100J), the flux density across the surfaceis a constant at 2.5 kG. This shows that the magnetic field is distortedfrom its natural state when it is placed in the system configuration ofFIG. 14.

Referring to FIG. 19A, a top view a permanent magnet arrangement for apermanent magnet asymmetric field system is shown in accordance withembodiments of the present disclosure. The arrangement includes threepermanent magnets and a perturbation element 108 arranged at aperturbation point. The three permanent magnets 106 are bar magnets withtwo of the magnets having their top sides having a north N polarity andthe other magnet having its top side having a south S polarity. Theperturbation and operation of the arrangement is substantially asdiscussed above in connection with other embodiments. The perturbationelement 108 may be actuated to perturb the asymmetric magnetic field(s).The resulting magnetic force from the perturbation(s) on the arrangementwill cause a body on which the magnets are arranged to rotate or movetranslationally.

Referring to FIG. 19B, a top view of a permanent magnet arrangement fora permanent magnet asymmetric field system is shown in accordance withembodiments of the present disclosure. The magnets 106 are magnetizedhorizontally (polarized along a horizontal plane—parallel to a mountingsubstrate or plate or body 102). The boundary line 192 approximates themagnetic boundary field line between the majority north field and theminority south field in the arrangement. The structure and operation ofthe magnet arrangement is similar to other embodiments discussed hereinand will not be repeated.

Although the embodiments of the present application have been shown anddescribed as being configured with permanent magnets, it is within thescope of the present disclosure to make one or more of the magnets ofany magnet arrangement described herein to be a permanent magnet, anelectro magnet, or a permanent magnet and electro magnet combination.For example, referring to FIG. 20, a magnet arrangement for a magnetasymmetric field system is shown in accordance with embodiments of thepresent disclosure. The arrangement includes three electro magnets 106that each include a coil 201 wrapped around a ferrous body to form eachelectro magnet 106. Each coil is configured to be energized with anelectric current in one current direction to cause the electro magnet tobecome magnetized in one direction and/or to be energized with anelectric current in a second current direction to cause the electromagnet 106 to become magnetized in a second direction, which is oppositeto the first direction. In some embodiments, the strength of theenergizing current to the coils 201 is configured to be changed suchthat the strength of the magnetic field generated by the electro magnet106 is selectable or adjustable or controllable.

In the embodiment of FIG. 20, the two top electro magnets 106 areenergized with current i₁, i₂ in the same direction to cause the magnets106 to become magnetized with a top side of the electro magnets 106showing a north N polarity, and the bottom magnet 106 is energized witha current i₃ in the opposite direction to cause the magnet 106 to becomemagnetized with a top side of the electro magnets 106 showing a south Spolarity. As discussed above, the electro magnets 106 may beindividually selectively energized in direction and/or strength to causethe electro magnets 106 to become magnetized as desired. The energizingof the coils 201 can be controlled by a controller (or other controlunit(s)) that controls or provides instructions for voltage sources V₁,V₂, V₃ connected to the coils 201. For example, the energizing of theelectro magnets 106 may be reversed to cause the top two magnets 106 tohave a south S polarity on top and the bottom magnet 106 to have a northN polarity on top. Then actuation of the perturbation element 108 in theopposite direction can cause a magnetic force in the opposite directionthan the previous magnetization arrangement. While all of the magnets106 are shown as electro magnets 106, it is within the scope of thepresent application for one or more of the magnets 106 to be permanentmagnets. In some embodiments, the electro magnets 106 may be coilswrapped around permanent magnets.

Referring to FIG. 21, a top view of alternative permanent magnetasymmetric field system 100K is shown in accordance with embodiments ofthe present disclosure. In this alternative embodiment, the permanentmagnet arrangements are similar to the magnet arrangements 104 shown inFIGS. 8 and 14, except the magnets 106 are magnetized horizontally(polarized along horizontal plane) instead of magnetized vertically(polarized along a vertical plane) as in the arrangements shown in theFIGS. 8 and 14 embodiments. In other words, the inner and outer sides ofthe magnets 106 in a horizontal direction of FIG. 21 have a polaritynorth N or south S. The bias magnet 106J is magnetized vertically(polarized along a vertical plane—perpendicular to the body 102). Theboundary lines 152, 154 approximate the magnetic boundary field linesbetween the majority north field and the minority south field in thearrangements 104C, 104D. The perturbation element 108 similarly has apolarity pattern opposite to side of the magnet 106 that portion of theperturbation element 108 is facing. In other words, the portions of theperturbation element 108 facing a magnet 106 with a south S side have anorth N polarity, and the portions of the perturbation element 108facing a magnet 106 with a north N side have a south S polarity. Theperturbation element 108 has a bottom portion facing the central magnet106J that is opposite to the polarity at the top side of the centralmagnet 106J, similar to the FIG. 15 embodiment. The structure andoperation of the system 100K is similar to other embodiments discussedherein and will not be repeated.

A schematic cross-sectional view of a permanent magnet arrangement ofthe permanent magnet asymmetric field system 100K of FIG. 21 along line22A is shown in FIG. 22A; and along line 22B in FIG. 22B. Similar to theschematic cross-sectional views of FIGS. 16A-16F and 17A-17F, when aferrous body perturbation element 108 is arranged at the perturbationpoint, the perturbation element 108 has an opposite polarity as thepolarity of the magnet 106 at a portion of the perturbation element 108facing the permanent magnet 106.

Referring to FIG. 23, a cross-sectional polarity diagram of aperturbation element 108 arranged in the permanent magnet asymmetricfield system 100K of FIG. 21 is shown in accordance with embodiments ofthe present disclosure. The perturbation element 108 shows a mostlysouth S field given that the majority field of the magnet arrangement isa north N field. The boundary line 230 approximates the magneticboundary field line between where the perturbation element 108 has anorth polarity and a south polarity.

Referring to FIG. 24, a top view of a permanent magnet asymmetric fieldsystem 100L is in accordance with embodiments of the present disclosure.The system 100L is similar to the system 100K of FIG. 21, except thatthere is no central bias magnet 106J arranged at the perturbation point116. The magnet arrangement 104 otherwise is the same and hashorizontally magnetized magnets 106 as opposed to the verticallymagnetized magnets of the systems of FIGS. 8 and 14. The boundary lines902, 904 approximate the magnetic boundary field lines between themajority north field and the minority south field in the arrangements104A, 104B.

A schematic cross-sectional view of a permanent magnet arrangement ofthe permanent magnet asymmetric field system 100L of FIG. 24 along line25A is shown in FIG. 25A; and along line 25B in FIG. 25B. Similar to theschematic cross-sectional views of FIGS. 16A-16F, 17A-17F and 22A-22B,when a ferrous body perturbation element 108 is arranged at theperturbation point, the perturbation element 108 has an oppositepolarity as the polarity of the magnet 106 at a portion of theperturbation element 108 facing the permanent magnet 106.

Referring to FIG. 26, a cross-sectional polarity diagram of aperturbation element 108 arranged in the permanent magnet asymmetricfield system 100L of FIG. 24 is shown in accordance with embodiments ofthe present disclosure. The perturbation element 108 shows a mostlysouth S field given that the majority field of the magnet arrangement isa north N field. The boundary line 260 approximates the magneticboundary field line between where the perturbation element 108 has anorth polarity and a south polarity.

Referring to FIG. 27, a top view of a permanent magnet arrangement for apermanent magnet asymmetric field system is shown in accordance withembodiments of the present disclosure. The permanent magnet arrangementgenerates an asymmetric field 270 using two magnets 106 magnetizedhorizontally (polarized along a horizontal plane—parallel to a mountingsubstrate or plate 102), and a bias magnet 106J disposed between the twomagnets 106, the bias magnet 106J being magnetized vertically (polarizedalong a vertical plane—perpendicular to the mounting substrate or plateor body 102) having a south pole pointing upward. The perturbationelement (or actuator) 108 would be disposed on the bias magnet 106J,similar to that discussed herein with the embodiment of FIGS. 14-15, anda force applied in the F arrow direction, and the default position beingin the D arrow direction.

Referring to FIG. 28, a top view of a permanent magnet arrangement for apermanent magnet asymmetric field system is shown in accordance withembodiments of the present disclosure. The permanent magnet arrangementgenerates an asymmetric field 280 using a single magnet 106 magnetizedhorizontally (polarized along a horizontal plane—parallel to a mountingsubstrate or plate 102), and a bias magnet 106J disposed at a horizontaldistance close enough the magnet 106 to create the desired asymmetricfield, e.g., about 1 inch. Other distances may be used if desired,depending on the desired asymmetric field strength and systemperformance requirements. The bias magnet 106J is magnetized vertically(polarized along a vertical plane—perpendicular to the mountingsubstrate or plate or body 102) having a south pole pointing upward. Theperturbation element (or actuator) 108 would be disposed on the biasmagnet 106J, similar to that discussed herein with the embodiment ofFIGS. 14-15, and a force applied in the F arrow direction, and thedefault position being in the D arrow direction.

The bias magnet 106J may be a disc magnet as shown or be any desiredshape, provided it has a magnetic polarity as described herein.

A bias magnet, e.g. bias magnet 106J, may be added to any of theembodiments at the perturbation point 116 to enhance the asymmetricfield effect and/or performance. In some embodiments, the bias magnetmay be arranged a distance away from perturbation point and/or where theperturbation element 108 is arranged to cause the body 102 to move, asdiscussed herein. In some embodiments, the bias magnet may be recessedbelow or into the body 102, which may further enhance the asymmetricfield effect and/or performance.

Also, the perturbation element 108 need only be made of a ferrousmaterial in the region where the flux field of the magnets are locatedand to a length or distance where the flux field effects on the element108 do not affect desired performance, e.g., up to a predetermineddistance above the top of the magnets. After this length or distance,the element 108 may be made of a non-ferrous material, such as plasticor other material. The actual distance or length will depend on themagnetic field strength of the configuration used and the desiredperformance output of the system.

The magnetic flux field boundary lines shown herein are approximate andindicative of the flux field when no perturbation element is positionedin the arrangement. The presence of the perturbation element 108 in anygiven arrangement may not substantially alter the flux field boundaries.Further, as the perturbation element 108 moves through the field (i.e.,when a force is applied to the element 108), the cross-sectionalmagnetic field polarity and/or strength along the length of, or at anygiven location on, the element 108 (e.g., as shown in FIGS. 23 and 26)may shift or change based on the position of the element 108 in the fluxfield.

In embodiments according to the present disclosure, the magnets arearranged to work facilitating rotation in structures such as windturbines, which may significantly reduce the input energy required toinitiate rotation of the wind turbine.

Dimensions provided herein are approximate and other dimensions may beused if desired provided they provide the same function and performancedescribed herein.

For the embodiments disclosed herein, the perturbation of the asymmetricfield causes a release of potential energy from the permanent magnetsinto kinetic energy in the form of angular or linear (translational)velocity or acceleration. We have found that small input forces actingon the perturbation element positioned at or near parallel to therotational axis (or perpendicular to the floor of the arrangement)causes an amplified output force due to such energy release (orconversion to kinetic energy).

While specific permanent magnet arrangements have been shown anddescribed as generating the asymmetric magnetic field(s) about theperturbation point(s), it is within the scope of the present disclosurefor the permanent magnet arrangement to be virtually any other shape orconfiguration, or number of magnets, as long as the arrangement isconfigured to generate an asymmetric magnetic field about theperturbation point(s). For instance, a permanent magnet arrangement thatwould otherwise generate a symmetric magnetic field about theperturbation point(s) but for the presence of magnetic field shielding,interfering or diverting structure(s) are within the scope of thepresent disclosure, i.e. the magnetic field shielding, interfering ordiverting structure(s) ultimately causes the permanent magnetarrangement to generate an asymmetric field about the perturbationpoint(s).

The magnetic field lines shown and described herein are an approximationof the location of the magnetic fields. The actual shape and location ofthe magnetic fields or field lines may be different than as shown and/ormay vary based on physical characteristics and materials of the system.

It should be readily understood that the magnetic polarity of themagnets of the systems and methods described herein can be reversed andachieve the same intended function and structure. Specifically, a magnetside (or surface) having north pole N polarity may instead have southpole S polarity and a magnet side (or surface) having south pole Spolarity may instead have north pole N polarity, and the permanentmagnet asymmetric systems and methods will function substantially thesame as disclosed herein.

While the present disclosure has shown and described the permanentmagnets as being circular flat magnets, cylindrical magnets and barmagnets, it should be readily understood that any permanent magnet shapeis within the scope of the present disclosure. The magnet(s) may differin shape and type. For example, the cylindrical magnets may be cylindersand/or cylinders with a central bore or hole defined therein in alongitudinal direction of the cylindrical magnet(s). Instead of thecentral bore (or in addition thereto), the magnets may be provided withblind bores. Magnets may be configured with the necessary central boreand/or blind bores for enhancing the magnetic fields thereof orgenerating the desired magnetic fields thereof. Other magnet shapes,such as rectangular magnets or flat magnets, may have transverse(through the thickness) bores or holes or blind bores for enhancement ordesired magnetic field shapes/strengths. Further, while various magnetshave been described as being separate magnets, it is within the scope ofthe present disclosure for the magnets to form a single, unitary pieceor structure. Also, any given permanent magnet described herein maycomprise a plurality of smaller permanent magnets that are stackedtogether to perform the same function and polarity as the givenpermanent magnet, if desired.

Although the invention has been described and illustrated with respectto exemplary embodiments thereof, the foregoing and various otheradditions and omissions may be made therein and thereto withoutdeparting from the spirit and scope of the present disclosure. It shouldbe understood that, unless otherwise explicitly or implicitly indicatedherein, any of the features, characteristics, alternatives ormodifications regarding a particular embodiment herein may also beapplied, used, or incorporated with any other embodiment describedherein.
